After five years, the music group No Doubt reunited to perform in Rockefeller Plaza in New York City to kick of the Today show's summer concert series.

Why such a long wait to go back on tour, you ask? "It's my fault," lead singer Gwen Stefani said on Friday. "I was in post-baby mode." She also pursued her solo career. The bandmates explained how excited they are to join forces again and perform for their fans, and revealed they will soon appear on an episode of Gossip Girl.

Check out the group's performance of their hit "Don't Speak" in the video below:
